Spring is here. Tauben and pigeons beware

OK, so it’s still cold out, but spring is here. Along with blackest humor. “Taubenvergiften im Park” was written by Georg Kreisler, “Poisoning Pigeons in the Park” was penned by Tom Lehrer. So: Did Lehrer steal the song from Kreisler, or was it the other way around? Lehrer had more chutzpah, and thanked Kreissler for “popularizing his songs in German”. Kreissler was sehr böse darüber.
